COLLABORATIVE RESEARCH: Interpluton Wall Rock Screens in the Sierra Nevada and their Bearing on Pluton Emplacement Processes

在复合基岩中保存分离单个侵入岩的变质岩分离屏是一个长期存在的、本身就很有趣的问题，它与侵入岩浆如何获得空间有关。研究人员已经对顶板垂坠进行了大量的研究，然而，岩壁屏风也可以提供对侵入过程的大量见解，但研究很少。这个由犹他大学、北卡罗来纳大学和波士顿大学的研究人员合作的项目将研究加利福尼亚内华达山脉的深埋岩屏幕的例子，这些特征在那里得到了很好的发展和展示。研究结果将有助于了解变质层是如何形成的，以及它们可能为了解岩体如何侵入地壳提供什么见解。

9814788Coleman The preservation of discrete screens of metamorphic rocks separating individual intrusions in composite batholithes is a long standing and inherently interesting problem that relates to how space is mad available to intruding magma. Considerable effort has been directed at roof pendants however wall rock screens may offer considerable insights into intrusive processes as well, but have been little studied. This collaborative project between investigators from the University of Utah, University of North Carolina and Boston University will study examples of pluton screens in the Sierra Nevada of California, where these features are well-developed and displayed. Results should help understand how metamorphic screens form and what insights they might offer in understanding how plutons intrude the earth's crust.
